Individuals, corporations, even governments have adopted carbon emissions as an indicator of our impact on the environment. As part of the Earth Day 2010 series of articles, this article will explore the “carbon footprints” of 5 common products: Tropicana Orange juice, a Big Mac, iPhone 3GS, Patagonia Nano Puff Jacket, and Nika Bottled water.

A carbon footprint of a product measures the total amount of carbon dioxide (CO2) that it produces from “cradle to grave.” This typically includes the amount of CO2 produced in the extended supply chain: from the extraction of raw material, to the manufacture, transport, and use of the product; ending eventually in the disposal and recovery of the product. Read, share, and enjoy (and yes, next time you buy something, take a look at its carbon footprint).
